2025年10月20日 14時24分46秒

H₂S or hydrogen sulfide is a colorless gas with a characteristic rotten egg odor and often appears in natural or industrial processes such as wastewater treatment, oil and gas exploitation or organic matter decomposition. This gas is toxic even at low concentrations, causing respiratory inhibition and loss of the ability to sense odors upon prolonged exposure. The following article by EMIN will help you understand the properties of H₂S, how to recognize risks and necessary measures to limit its impact on health and the working environment.
